Thanks Bill. I definitely do not have those inserts. Very interesting.
Based on what I'm seeing, I'm not entirely sure this is a simple retrofit. There is a plastic mount on the back of the panel.

No problem, Stefan. Actually, I don't think it would be too bad to add them. I don't think you would even need to remove the trim panel. My guess this that they've just added a slot for #10 in the realoem diagram, the expanding nut. Unless you don't even have that recess for the dimple already, that is.

Depending on how adept you were with a dremel, the benefit might be well worth the effort.
